1 INTRODUCTION TO THE TP10, TP20 AND TP30 TILLERPILOT

The TP10, TP20 and TP30 Tillerpilots combine highly sophisticated electronics with advanced
software and powerful mechanical drive to provide accurate and reliable steering performance
under a variety of different conditions with minimal current consumption.

TP10 – is suitable for tiller steered sailing yachts up to 10M (34 Ft) in length.

TP20 – offers the same facilities as the TP10 and is fully compatible with the Navico Corus

instrument system to provide a complete navigation system. Options offered include connection to
an external compass, wind sensor or navigational receiver together with additional remote control
facilities.

TP30 – offers the same facilities as the TP20 with an improved re-circulating ball screw drive and
is suitable for tiller steered sailing yachts up to 12.8M (42 Ft) in length.

The main components of the Tiller Pilot are listed below:

Electronics PCBs

Early versions

TP10 PCB (TP10 only)
TP30 PCB (TP 20 & TP30)

Current Versions. The same PCB is used for all products. The wiring
loom carrying the NMEA data is left disconnected in the TP10.

3 ASSEMBLY INSTRUCTIONS

General Assembly : TP10

Motor and Drive Assembly. The Bottom Case Assembly is supplied fitted with appropriate

cables. Refer to detail in Drawing Number E03504 and insert the Push Rod Seal E00747, which
has a taper inner bore, into the case with the larger bore of the seal facing outwards. Fit “O” Ring
190026, spacer E02870 and End Cap E02495 and push home. Fit Retainer E03084 and secure
with 2 screws 200002 to hold the end cap, ensuring it is pushed fully in when the two screws are
tightened. Using a small brush, grease the ‘trough’ area and the bore which houses the seal, “O”
ring and spacer. Insert the Drive Assembly E03264 ensuring that the bearing slots into the bearing
housing and the drive belt 280027 is fitted around the pulley. Insert the Motor Assembly E02788
fitted with front and rear Motor Mounts E02502 and E02503 ensuring that the blue wire is
uppermost, the motor sits snugly into the bottom of the retaining slot and the drive belt is engaged
over the motor drive pulley. Check that the motor, belt and drive screw assembly move freely. Fit
Bearing Clamp E02497 on two Nylon Spacers 200115, one on each screw 200137, into the case
bottom and secure the bearing with the two screws. Refer to the sketch below and check that the
belt tension is within +/- 3mm.

Fit the Tiller Connector E02607 into the end of the Push Rod E02522 and screw in, finger tight.

Hall Effect PCB. Fit the Hall effect PCB onto the 2 pillars using 2 nylon washers 200037 as
spacers between the pillars and the PCB, and 2 screws 200139. Ensure that the separation
distance between the Magnets (E03208), seated in the 71 Tooth Pulley (E02505), and the Hall
Effect Devices (140010) does not exceed 1mm.

Main PCB. Feed the power, motor and feedback leads through the 2 grommets 190036 and the
appropriate grommet in the PCB Assembly cover and solder the connections to the PCB. Refer to
drawing and push PCB Assembly firmly onto the four bosses in the PCB Cover E02680. Clip the
compass Assembly E02637 into the Drilled PCB Cover E02680, it can only be fitted one way
round, ensuring that the lugs on the compass assembly line up with the 2 holes in the PCB cover
and push in. Refer to drawing E03504 and ensuring that the wires from the compass to the
connector lay over the PCB, insert plug into the socket on the PCB. Ensure all wires are clear of,
and not fouling the PCB cover seal, and position the PCB Cover complete with the PCB and
compass into the Case Top Assembly E02612. Screw down the PCB cover with 6 screws 200139
and fully tighten. Position the two grommets into case top, and push home into the two slots.
Wrap the ‘Wits” fixing 200196 around the cable loom, and using a screw 200139 fix into the top
cover.

Main Seal. Fit the pivot pin into the square section at the rear of the prepared bottom case
ensuring that the pin hangs out of the case with the notch on the pivot facing towards the operating
rod of the tillerpilot. Fold the metal pin into its recess in the lower case. Position the Case Seal
E02498 onto the case bottom ensuring it is pushed fully into the grooved housing. Carefully lift the
case seal from around the area of the pivot pin and using a cotton bud apply Dow Corning 1205
Primer 260029 to the case. Fill a small hypodermic syringe with Dow Corning 3140 Silicone
sealant 260001 and run a small bead of sealant completely around the case seal in the area of the
square as shown below.

Refit the seal onto the case.

Final Assembly. Carefully position the case top onto the bottom ensuring that the case seal is
correctly located all round, squeeze the top and bottom halves of the case together, and fit the 10
screws 200088. Tighten down evenly all round in the sequence shown below:

Post Assembly Test. Remove the Tiller Connector E02607 and push the Tillerpilot Test Syringe
Part No. TP-SRY over the end of the Push Rod E02522. Depress the syringe piston and release,
the piston should return to its original position indicating that the integrity of the case seal has not
been compromised during fitting. Remove the Test Syringe and refit the Tiller Connector.

General Assembly : TP20

Refer to Drawing No. E03505. Assembly is identical to the TP10 with the following exceptions:

Case Bottom. The case bottom includes a third wiring (communications) loom to carry NMEA and
CANBUS data.

PCB Cover E02681. The PCB Cover is drilled with a third access point and grommet to accept
the NMEA and CANBUS data leads.

General Assembly : TP30

Refer to Drawing No. E03506. Assembly is identical to the TP20 with the following exception:

Drive Assembly E02618. The Drive Assembly employs a re-circulating ball screw. The assembly
is held in place by the metal mounting plate sitting in the mounting slots in both top and bottom
cases and drive belt tension is adjusted by the inclusion of spacing shims E02754 as required.
